LAFAYETTE — The Louisiana-Lafayette football team added two more positions to its vacancy list when it decided not to bring back defensive line coach Tim Edwards or outside linebackers coach Matt Wallerstedt.

The school confirmed the moves with a brief news release Sunday. Head coach Mark Hudspeth declined to comment on the decision in the news release, as did other coaches whom The Advocate reached out to.

The Cajuns now have three assistant coaching positions to fill this offseason. Former defensive backs coach Tim Rebowe is Nicholls State’s new head coach; he moved on after the Ragin’ Cajuns’ New Orleans Bowl victory against Nevada.

The Cajuns must replace 75 percent of their defensive coaching staff — an entirely new endeavor for Hudspeth. It’s the first time during his tenure that the coaching staff will face massive offseason reconstruction. When the 2014 season started, all but one member of Hudspeth’s original staff remained in place, but now every defensive assistant from that staff has either been let go or has moved on to another job.

Both Edwards and Rebowe were members of Hudspeth’s original staff — as was former linebackers coach David Saunders, who resigned in the middle of the season.

Edwards joined the Cajuns in 2011 after spending three seasons at Florida A&M as co-defensive coordinator, defensive line coach and recruiting coordinator. He played at Delta State with Hudspeth before playing six years professionally in the NFL and CFL.

Several Cajuns defensive linemen developed nicely under Edwards, including Christian Ringo, who spent his entire career with Edwards as his position coach before breaking the Cajuns’ single-season sack record this year.

Wallerstedt joined the staff as a consultant in the middle of the 2014 season after he abruptly resigned from his post as Texas Tech’s defensive coordinator in September. Wallerstedt took over the outside linebackers position after Saunders’ resignation in November.

Hudspeth was asked several times during the season to offer an assessment of his staff — including Wallerstedt’s performance — but each time Hudspeth said he would take time to evaluate his assistants after the season.

Previously, the only offseason change Hudspeth had made was when he hired defensive coordinator James Willis before the 2013 season.
